PHYSICS HELP PLEASE, WILL AWARD BRAINLIEST :) For the circuit shown with a 12.0 V battery, what are the currents through each resistor and the voltage drops across each resistor?

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

At 20∘c, the hole in an aluminum ring is 2.800 cm in diameter. you need to slip this ring over a steel shaft that has a room-temperature diameter of 2.804 cm . 1. to what common temperature should the ring and the shaft be heated so that the ring will just fit onto the shaft? coefficients of linear thermal expansion of steel and aluminum are 12×10−6 k−1 and23×10−6 k−1 respectively.

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.
